- IMPROVEMENT- mjGAs-REToR'rs.

'I .he SoheduIereIez-red to in these'Letters Patent and making part .01 the same Be it known that. 'l, EDWIN '1)."1\[(:Ga.-\c1u-ix, of the city, county, and fitate of New York,have invented a new and 'ns'cl'nl lmprtwement in Gas-'lictorts; "and I dohereby declare that the following is a full,

clear, and exaet description (lf,t-ll6' saimarel'erence being) had. tothe accompanying drawing fiirniing, part of this specification.

This invention consists in 'n'ornling' a horizontal gas-retort with a jacket,"which extendsalong, and all over its top. and sides, and over its rearcnd, and which communicates with the lowest part of the interior of the retort, and lorms the commnnicathm between the retortand the stand-pipe; the object being to insure. thedecomposition and conversion into permanent gas of the condensible vapors which escape from theretort, and which, in making gas in ordinary retortsf form or are. collected witlrthc tar.

Figure 1 iut he drawing is a central-longimdinal vertical sectiou ot' a gas-retort, \rith myimprovcment.

Figure 2 is a transverse section of the same.

Similar letters of reference indicate corresponding parts in both figures. 1

The improvement is applicable to retorts of various forms, but a retort of the ordinary D-form representedin the drawing serves as well as any other to illus: trate the invention. The retort maybe made of-castiron or offire-clay. I

A is the body of the retort, of'ordinary form and B is the jacket, extending all along, and over the top and sides, and over the rear end, and epmmunicab ing'with the interior of the retort by means of .a narrow transverse opening, (1-, cxternli ng'alang a; bottom of the rear end.

Atthe front end of the jacket, in the upper part thereof, is an opening, b, \vith which the stand-pipe for leading oil the semis connected. I The retort-head needs only to cover the body of the retort,lcavmg the opening bontside for the'connection of the pipe. "lhe retort. thus jacketed maybe arranged m the bench orii n-nace in the usual -\ray, and, as the acket is-dirc'ctly exposed tothe-he'at, and the heat can only [penetrate the. sides, top, and" rear end. of. the retort, through the jacket, thelatter must be hotter than the body of the retort. Th'egas generated, and 'rapors evolved, in the body or inner portion of the retort be- V 1 ing, owing 'to the position of the opening a, close to the'bottom' oi the retort, compelled, for'the most part, "to descend througlrthe body of the coal orj material \Vhat I cla-iina-s my invention, and desire to secure by Letters Patent, is-- V ThejacketB, covering-the top, sides, aud rear end of the retort, and eoimnunieat-ing with the iuterim'jor body thereof, by means of an openinge, arranged as ,herein described.
